  o : object to be compare with.
  Return :
  true : if o equals argumented object, else false.
• hashCode() : java.lang.Character.Subset.hashCode() returns the hashCode value of the Subset..

  public final int hashCode()
  Parameters :

public class CharacterSubsetDemo extends Character.Subset

{

`` CharacterSubsetDemo(String s)

`` {

`` super (s);

`` }

`` public static void main(String[] args)

`` {

`` CharacterSubsetDemo a = new CharacterSubsetDemo( "geeks" );

`` CharacterSubsetDemo b = new CharacterSubsetDemo( "for" );

`` boolean check2 = a.equals(a);

`` System.out.println( "Is a equals a ? : " + check2);

`` check2 = b.equals(a);

`` System.out.println( "Is b equals a ? : " + check2);

`` System.out.println();

`` int check1 = a.hashCode();

`` System.out.println( "hashCode " + a + " : " + check1);

`` check1 = b.hashCode();

`` System.out.println( "hashCode " + b + " : " + check1);

`` System.out.println();

`` System.out.println( "a : " + a.toString());

`` System.out.println( "b : " + b.toString());

`` }

}

Output :

Is a equals a ? : true Is b equals a ? : false

hashCode geeks : 366712642 hashCode for : 1829164700

a : geeks b : for
